Description
Technical field
The utility model relates to combustion gas tool security protection technology field, particularly a kind of pulse firing formula combustion gas tool safety guard that stops working.
Background technology
At various combustion gas tools particularly in the household gas apparatus; generally all to be provided with the accident extinguishing safety guard; in existing this type of safety device; a kind ofly mainly form by pulse firing controller and self-priming magnetic valve; when the combustion gas tool is worked; the pulse firing controller sends the high-voltage pulse spark and strong in short-term absorbing current is provided simultaneously and keeps electric current and makes the adhesive of self-priming magnetic valve under switch motion control; combustion gas flows to burner through the self-priming magnetic valve; behind the high-voltage pulse spark ignition; pulse firing controller ion induction end receives the flame ion electric current; stop high-voltage pulse output; and continue to provide and keep electric current and make the self-priming magnetic valve keep attracting state; when switch motion resets or detect less than gas current because of accident extinguishing; the self-priming magnetic valve is kept electric current and is promptly disappeared; armature discharges, and cuts off blast tube and plays the safeguard protection effect.Another kind mainly is made up of hand magnetic valve and thermocouple, when Gas Utensil Lighting, the armature of handle type solenoid valve is pushed into the attracted position by push rod, combustion gas handles that type solenoid valve flows to burner and by after being lighted, the thermocouple that is installed in the burner side generation electromotive force that is heated, keep adhesive up to the hand magnetic valve that its electric current can make winding be connected in parallel with it, still be in attracting state after push rod resets.When burner was flame-out, the residing environment temperature of thermocouple slowly reduced, and the electric current that is produced also slowly reduces, and the hand magnetic valve just takes off valve and resets during to some current values, turn-offs combustion gas.
Above-mentioned two kinds of safety guards all can play accident extinguishing safeguard protection effect.The circuit of the former pulse firing controller is comparatively complicated, as when lighting a fire the pulse igniter except providing earlier the high-voltage pulse, must strong absorbing current be provided simultaneously and keep electric current earlier to the self-priming electromagnetic valve coil, allow the adhesive of self-priming magnetic valve, pulse igniter also must have a delay circuit in addition, still misfire through a period of time, then will stop igniting and stop keeping electric current, the self-priming magnetic valve automatically resets; After catching fire as point, the flame ion electric current that flame-sensing needle provides is through amplifying, carried out by circuit after the shaping again the action that stops high-voltage pulse output and continue to provide self-priming valve to keep electric current till flame-out.The electric current of keeping of flame-out back self-priming magnetic valve promptly stops to supply with.When controlling a plurality of burner simultaneously, control circuit is more complicated.Simultaneously, self-priming electromagnetic valve structure relative complex, the electric current of keeping adhesive is also bigger, is to adopt manual combustion gas tool to use this protective device obviously more to dislike complex structure, cost height, reliability decrease as igniting therefore.If battery operation, then battery service life is also short.Back a kind of safety guard manual magnetic valve simple in structure, need not to provide separately power supply just can work; cost is lower than the former, but thermocouple surface can produce carbon deposit and makes output potential descend and the adhesive reliability that influences manual magnetic valve after work a period of time.In addition, combustion gas just can be kept the adhesive of hand magnetic valve armature by the electric current that must be produced after lighting when the after heat galvanic couple reaches uniform temperature after a while, operate trouble consuming time; When under normal circumstances running into accident extinguishing, manually magnetic valve can cause a large amount of combustion gas to leak because of the thermal inertia of the thermocouple thermal field of living in pass valve of delaying time therefrom, brings serious potential safety hazard.
Summary of the invention
The technical problems to be solved in the utility model is: during, cost low manual pulse firing combustion gas tool simple in structure when adopting, under normal or non-normal flameout situation, can both turn-off fuel gas path rapidly reliably.
The technical solution that the utility model proposed is such: a kind of pulse firing formula combustion gas tool safety guard that stops working; comprise burner 6; igniting pin 8; hand magnetic valve 9; pulse firing controller 1; valve body 10; described valve body 10 is equipped with the start-up circuit switch 11 with push rod 12 interlocks; the push rod 12 that back-moving spring 15 is housed contacts with the sealing valve block 13 of band back-moving spring 16; hand magnetic valve 9 be installed on the valve body 10 and in be provided with the electromagnetic valve coil winding; be provided with start-up circuit 3 in the described pulse firing controller 1; high-voltage pulse generator 2 and external direct current power supply; switch 11 outputs successively with start-up circuit 3; high-voltage pulse generator 2; the igniting pin 8 that is located at burner 6 next doors is electrically connected; valve body 10 is provided with fuel gas inlet 5; its gas outlet is communicated with burner 6 by pipeline; the valve block 13 and the valve port 14 of hand magnetic valve are tightly connected; also be provided with flame ion current amplifier 4 in the described pulse firing controller 1; be provided with flame-sensing needle 7 in burner 6 one sides; described flame-sensing needle 7 signal output parts and flame ion current amplifier 4 inputs are electrically connected, and these amplifier 4 outputs and hand magnetic valve 9 coil windings are electrically connected.
During work; promote push rod 12; switch 11 actions; manually the sealing valve block 13 of magnetic valve 9 pushes away valve port 14 and is pushed to the attracted position; the high-voltage pulse generator 2 of pulse firing controller 1 produces high-voltage pulse; produce the pulse spark through igniting pin 8; light through the combustion gas of valve body 10 to burner 6; after flame-sensing needle 7 touches flame; flame ion current amplifier 4 inputs that the flame ion electric current enters the pulse firing controller through " " line and burner 6 " " the formation loop; the flame ion electric current is after amplifier 4 amplifies; provide operating current by flame ion current amplifier 4 outputs to the winding of hand magnetic valve 9; withdraw from as valve body push rod 12 this moment; switch 11 resets; pulse firing stops; but hand magnetic valve 9 is still kept adhesive; flame burns away; no matter up to flame is that manpower cuts off source of the gas or accident extinguishing; gas current is zero; gas current amplifier 4 electric currents of pulse igniter are output as zero; hand safety valve 9 resets; turn-off blast tube, thereby play the safeguard protection effect.
The structure of hand magnetic valve of the present utility model and existing hand magnetic valve is basic identical, its difference is that the coil windings of hand magnetic valve adopts little line footpath, multiple secondary winding, because the utility model is not to adopt thermocouple that the electric current of keeping of magnetic valve is provided, thereby the long problem of valve delay time of taking off can not appear causing because of hand electromagnetic valve coil number of ampere turns is excessive, therefore the coil windings number of turn is many more, it is required that to keep operating current more little, minimum can be below 1 milliampere, general manual line solenoid valve loop diameter is between φ 0.04～φ 0.09mm, and umber of turn is between 400～150 circles.
